[Review of pseudocysts and bone lacunae of the jaws].

Non-odontogenic cystic lesions and so-called "pseudocystic" lesions of the jaws are reviewed, summarizing most recent data from the literature and with illustrations. Pseudocyst lesions include the aneurysmal bone cyst, the solitary bone cyst and Stafne's lacunae. Non-odontogenic cystic lesions, characterized by the presence of a non-odontogenic epithelial lining, are represented by the nasopalatin cyst, the nasoalveolar cyst and an entity currently covering globulomaxillary, midline palatin, midline mandibular and midline alveolar cysts.
